主　　题：copper matrix nanocomposites pH-responsive active protection synergistic effect 

摘      要：An active protection coating for pH-responsive was *** hollow mesoporous silica microspheres(HMSNs)were loaded with 2-mercaptobenzothiazole(MBT),and then they were coated with chitosan(CS).The composite microspheres were in the range of 650−750 nm in ***-HMSN-MBT coating had a faster repair rate under acidic conditions by synergistic effect between CS and *** repair rate under alkaline conditions was slowed *** active protection performance reached the strongest after 3 d *** corrosion inhibitor release mechanism was optimized to extend the service life of the coating and to achieve long-term service of the copper substrate.
